Clemans, 69 N. 6th St., Rio Vista, Calif. 94571 Filed Mar. 6, 1967, Ser. No. 620,777 Int. Cl. A471 13/08; B27g 17/04 10 Claims ABSTRACT OF THE DISCLOSURE A paint scraper for use as a hand tool in removing loose or scaling paint from stucco, concrete, cement block, wood or other painted rough surfaces. It consists of a handle, contoured to fit and be comfortably held in ones hand. Secured at one end, either permanently or removably, are a number of flexible, metallic tines extending at right angles of the length of the handle. The tines extend from a metal base, and one or more bases may be used, as desired.

The paint scraper held in the hand is pushed back and forth on the surface to be scraped. Tines are operative in both directions. The act of scraping keeps the tines sharpened. Should one or more tines become bent, they may be straightened by pliers or hammer. The metal is one of suitable characteristics, such as steel, stainless or otherwise, or any other suitable metal. If intended for use as a cheap, throwaway tool, its cost is kept down by permanently securing the tine base in position, as by rivets. Also, the handle and tines may be of one piece of metal. If intended for longtime use, suitable threaded studs, screws or bolts are used, either threaded into the handle, or secured by nuts or threaded sleeves or the like, depending on the composition of the handle. The handle may be of wood, or of hard plastic, such as Bakelite.

OBJECTS A further object of this invention is to provide a hand tool for scraping paint which comfortably fits the hand in operation, and wherein scraping tines are provided which are used in a back and forth direction, thus increasing the speed of operation, and which are self sharpening as the tool is used.

A further object of this invention is to provide a hand tool capable of carrying the functions set forth in the abstract above and having the construction described in such abstract.

DESCRIPTION OF THE DRAWINGS With the above and related objects in view, this invention consists in the details of construction and combination of parts, as will be more fully understood from the following description, when read in conjunction with the accompanying drawing, in which:

FIG. 1 is a bottom plan view of the hand tool paint scraper of this invention.

FIG. 2 is a partly sectional view on line 22 of FIG. 1.

FIG. 3 is a tine end view of the hand tool.

FIG. 4 is a perspective view of a set of tines integrally extending from a common metal base.

FIG. 5 shows a one piece handle and tines and tine base.

DETAILED SPECIFICATION There is shown at the hand tool of this invention consisting basically of a longitudinal handle 12 and a plurality of right angled or L-sha'ped paint scraping tines 14. The tines 14 are made of suitable flexible, resilient metal or material, secured to and extending from a large end 16 of the handle 12. While stainless steel is a pre- 3,530,524 Patented Sept. 29, 1970 ferred material, any other steel or metal having suitable characteristics may be used for the tines 14. A plurality of the tines 14 extend integrally from a common metal base 18 inserted in a slot 20 through the handle end 16 between two of the opposite surfaces 22 of the handle 12.

A securing pin 24 is inserted through an aperture 26 in the handle end 16 and through an aperture 28 in the tine metal base 18 to hold the tine base 18 securely in the slot 20 of the handle end 16. While this pin 24 may be riveted into place, for a permanent fastening in a throwaway form of this tool 10, it is here shown as threaded at one end at 30 and provided with a screw driver cooperating kerfed head 32 so that the tines, when worn out, may be readily replaced. Obviously, any other type of suitable readily removable and replaceable securing means may be used, such as a bolt and nut or wing nut, a Phillips screw, and female threads may be in the handle as shown, or may be in a threaded sleeve. Any other type of conventional securing means may also be used.

It will be noted that the right angled teeth 34 of the tines 14 are tapered at toward their tip ends, and such taper may start at the tine base 18 as shown. Two tine bases 18 with their integrally extending tines 14 are shown but, if desired, a single tine base, or three tine bases may be used.

The other end 36 of the handle 12 is smaller than the tine handle end 16, and between the handle ends 16 and 36, the longitudinal sides of the handle 12 are recessed as at 38 so as to make it comfortable to hold while in use scraping paint. Without in any manner limiting the invention, it is pointed out that the preferred dimensions are as follows: The overall length of the handle is six inches, its thickness is three-fourths of an inch. The width of the small end 36 is one and three-eighths inches, the width of the larger end 16 is two and onehalf inches,

. the slot 20 is one-sixteenth inch deep and extends one inch into the handle end 16; the tine base 18 is one and one-half inches long, one inch of which being supported in the slot 20. The tine teeth 34 extend one-half inch below the lower surface of the tine base 16, and the tine base 20 and tines 14 and teeth 34 are one-sixteenth of an inch in thickness. The added width of the tine bases is one and three-quarters of an inch, whether there be two time bases 18 as shown, or one or three bases. At its narrowest area, the handle is fifteen-sixteenths of an inch in width.

In operation, the handle 12 is grasped between its enlarged ends 16 and 36, the fingers curling about the recessed side 38, and the right angled tine teeth 14 are scraped back and forth over any loose, scaling, peeling or blistering paint on any rough surface, such as stucco, concrete, cement block, wood or other painted rough surface. It is particularly useful for spot peeling on interior, as well as exterior building surfaces. The tapering of the tine teeth 34 reduces the bending sideways while scraping, but should they bend, they can be straightened by use of a hammer or pair of pliers Without breaking. The teeth 34 are self sharpening when used on stucco, concrete or cement block; preferably, tempered steel is used to resist bending. This hand tool 10 takes the place of sand blasting in many cases, and is useful to both amateur and professional.

In FIG. 5, a one piece tool 42 is shown, having the same shape and appearance as the tool 10, except that the handle 44 with similarly recessed sides,- is integral with the time base 46 and the tines 48 and tine teeth 50. The one piece scraping tool is of suitable material such as steel or other metal.

Although this invention has been described in considerable detail, such description is intended as being illustrative rather than'limiting, since the invention may be variously embodied, and the scope of the invention is to be determined as claimed.

Having thus set forth and disclosed the nature of this invention, what is claimed is:

A back and forth scraper hand tool for paint, stucco and like rough surfaces comprising an elongate handle, and a plurality of flexible side by side, L-shaped scraping tines extending longitudinally from and secured in one one of said handle, the short leg of the L-shaped tines extending at right angles to the long end, said long end being secured in said handle end, said short L-leg providing a scraping tooth, said scraping tooth being of substantial width and having a fiat rectangular tooth end face, parallel to said long L-shaped leg of said tine.

2. The tool of claim 1, said handle being longitudinally recessed between enlarged ends to be readily held in the human hand.

3. The tool of claim 1, a plurality of said tines extending from a common metal base secured in said handle, each said tine having said tooth extending in the same direction from said common base.

4. The tool of claim 3, each said tine tapering from said base toward its tooth tip end.

5. The tool of claim 3, said handle end having a slot extending therein intermediate of and parallel to two of its opposite surfaces, and securing means extending through one of said opposite handle surfaces and fastening said time base in a slot in said handle.

6. The tool of claim 5, said securing means composing a pin extending through one of said handle surfaces into cooperation with said tine base in said handle end slot.

7. The tool of claim 6, said pin being threaded, said tine base having an aperture through which said threaded pin extends.

8. The tool of claim 3, said tool having a plurality of tine bases, each with a plurality of tines, secured in said handle end slot in side by side relation.
